More improvements and bug fixes.

The initial graph comes up quicker. There is just a 1 second pause to collect the initial samples. It will wait for at least three samples to be available in any case.

The handling of the "mille" and "seconds" buttons has been improved.

Probes can be removed by deleting their text and hitting carriage return. A carriage return is required if a probe text is edited.... read more

I did a cleanup and removed some debugging before uploading the previous version. Unfortunately a required global declaration was removed and the TCL script died while starting up. THis has been corrected, and obviously you should always test even after trivial edits...

Another update with bugfixes and improvements.

The default type of terminal for Gnuplot has been changed to "x11". At least on newer Linux systems it was using type "wxt" and this either required more I/O to update or miss labeled the y axis. It showed 10x as many interrupts to update over a network connection.

When adding more probes, the data logging is automatically restarted when the absolute or delta ("abs" or "del") buttons are selected for the first time.... read more

Two more bug fixes.

On a system that was loaded it was possible for the graphing program to exit because the log file was empty. We now wait 2 seconds for the file to be created and initial data to be written to it by the logging program.

It was possible to start multiple copies of the logging program by repeatedly hitting the "start" button. We check now and do not create another process until the old one is removed with the stop button. This happens automatically when changing probes or sample rates etc.... read more

A bug fix for situation where user selects to refresh display quicker then the sampling interval. In those cases there was an attempt to display with no data available.

Another fix to automatically stop and restart everything when the sample rate is changed.

The tar file was changed to place the source files in a directory named KernScope.

The Readme file has been updated with some description of KernScope's pieces and information on how to specify values in /proc and /sys to be displayed.
